arm64: dts: qcom: qcs6490-rb3gen2: add rmtfs node

Browse source

Downstream kernels for RB3 Gen2 don't specify the RMTFS address, instead
the kernel is supposed to allocate rmtfs buffers dynamically. The
upstream kernel doesn't support dynamic allocation of RMTFS buffers, so
use the fixed allocation. The RMTFS node (and corresponding interface)
is required for the modem DSP to work (which otherwise would crash).
